To all whom, it may concern Be it known that we, Anrnrtu l. and Oscar: Scnmrznnn, citizens; of the United States, residing, respective y, in (lin invented certain new and useiul l'lPl'GVLr ments in Speed Indicating or Controlling Mechanism, of which the ii'ollor'ing is a specification.

Our invention relates to soeed iodicrting or controlling mechanism applirable, for instance, for indicating or cortrolling the speed of a traveling vehicle, siuh as an auto mobile, and is arranged to be operated by a suitable power element, which. may be instanced as the driving axle of the vehicle.

Our invention has for its object the pro vision of means whereby the. travel of the vehicle may be controlled by its speed; further, the provision of novel means whereby the speed of the vehicle or other device to which our improvement is applied may be indicated; further, the provision of novel means embracing a con eyor mechanism adapted to actuate a resistance member, through which parts are actuated to indicate speed or to control parts; further, to etl'ect indication or controlling of the speed o means of a viscous fluid, the movement whereofactuates a member or members for The invention will be further readily understood from the following description and claims, and from the drawings, in which latter:

Figure 1 is a front elevation of our improved device, with the front of the housing partly broken away. Fig. 2 is a vertical cross-section of the same on the line of Fig. 1. Fig. 3 is a horizontal cross-section of the same on'the line y-y of Fig. 1. Fig. {i is a detail in cross-section on the line 02-a2 of Fig. 1; and, Fig. 5 is a diagrammatic representation of a preferred form wot electrition.

The housing is shown as a su: table box, which may be attached. to a suitable part, as to the dash-- bo: rd of an itlZtOl'l'lObilQ, preferably in View of he operator for exposing an indicator ll to he vision of the o erato.'.

The casing; 5 Luis an inlet port 12 COilUIllh nit; ting with the I poi-1 13, also protein 3' communicating with the reservoir. The casing is slown as 00111 prising uprights Li, secured to the bottom of the resenvoir.

The fluid convc 'er is adapted to discharge against an end-member which is movable, the increment thereof being controlled by the speed of said discharge. Vi e have shown this end-nieniber as comprising a cup 21, repr entod as an inverted cup, having an end 22, against which the fluid-discluzre'e take: place. The wall of the cup is received IbOUT the tubular casing 5, preferably guided in axial movement by guides 23 on the cas- 1n 7 Passages 24 are located between the outer wall it the tubular casing and the wall of the (1113, and preferably \hc end of the casing is nor ually spaced from the end-member, as by a space 25 for normally permitting slight passage of fiuid through the casing without actuation of said end-member. As the speed of the screw is increased, the force or pressure oi the fluid against the end-nieinber will also increase and thereby cause movement oi the endanernber, whereby the said space 25 between the end of the wall of the casing and the endmeniber is increased for iii permitting" increasing of the fluid between said casing and endfiznember. The

-amount of movement of the end-member is l controlled by the speed or pressure or the fluid discharge from the fluid conveyor. The end of the casing adjacent to the endmember is preferably of out ard flaring form, as shown by the tiaringiip 9 6, fornr ing a bell-shape mouth "for the end of the casin The end-member terms a floating member controlled by the fluid, which in turn. con,- trols the mechanism ope ated on by the apparatus. The end-member or floating member acts on an actuated member, which preterably affects an electrically controlled oil cuit or. circuits. W e have shown the same as affecting two electrically controlled devices, instancing the same as a spark-plug 3i. and. an incandescent lamp 33, these devices being shown as cxemplifications and'not as limitations. Thus represents an actuated member, shown as a bell-crank arm, which has on it a pointer 36 oi": the indicator 11, the scale of which is shown at 87, the scale and pointer being exposed through the covering in an exposure-opening 38 oi the housing. The bell-crank arm is pivoted. t 39 the housing.

40 is an arm pivoted at 41-1 to the housing. It preferably has loose articulations with the cup, shown as slots 42 in the arm, and pins 4L4. on the cup, the slots being shown in the spread walls 43 of the arm received about the hub of the cup.

15 is a link articulated with the arm -10 and the actuated member 35. This link is. shown adjustable, as by having a bearing;- piece 46 journaled about a pin t? for torming the articulation with the arm. L0; this bearing-piece having a threaded socket L9, in which the threaded end 50 of a rod 51 is received and held in place by a lock-nut 52, the rod having a bearing about a pin 5-iforming the articulation between the lini; and the bcll-crank arm 35.

It desired, a resistance member may is provided upon which the end-member act and which is primarily for the purpose 0 insuring against vibration ct parts due, tor. instance, to the jolting of the vehicle or actuation of the engine. We have shown this resistance member as comprising spring (31 received about a positioi'iing rod 62 acjustably screwed into a threaded bearing 63 of the' housing and heldsin place by a locknut 6a.

65 is an adjustable collar, adjustable about the threaded end 66 of the rod,- and held in place by a lock-nut '67.

68 is a collar slidable on the rod and bear ing against the arm 40, the spring being between the collars. The adjustable connection of the rod with the housing adjustably positions the" .zation of the spring with relation to the arm 10, and the adjustmember which is adapt e have show '1 the same an a in having on it electric term rials TL, one or both oi which may be en ployed. These terminals are arrang to 2! in lnction with elcctrio tern'iinals Ti, Y5, simninariiy positioned on the housing. The arm "at is preferably secured to a rock-shaft '26 journaled in bear ings T7 the housing. ihe roclii-shatt has on. ita part 78 arranged to be actuated by the/arm 35, this part being; shown as a conc tac'bpart, arrai'iged to be contacted by the striker-part T9 on the arm 35, the same being actuated preferably when the arm 35 has been moved to one or its limits of movement, or at the point oil actuation for which adj ment has been made. 'ihe contact-- part "[8 is shown 80, istably secured to the reclashaft tor (let rung its moment oi; actuation, and

it has a contact-thee Si. a1. :tilgGCl to be st uck by the striker-part T9 in the various ions to which the contact-part may be adjusted.

With the arrangement stated with the apparatus adjusted, for instance, for 25 mile limit of speed travel, when the driving axle has reached said soeed, the e pressure of the fluid passing through the fluid conveyer against the end-member u ll cause engagement of the striker-met w the contact-part 78, whereby the arm I lQ swung for causing creaking of contact between the terminals 2'2, 7%, and ei'igegeme al I I supplying the spark-plug 'ill intered and the circuit supplying the signel it i will be closed, thereby notifying the operator that the limit of speed has been reached and causing cessation of propulsion of vehicle.

We have also shown provision whereh one of the circuits may be rendered inacti while the other is maintained active may be desired, for instance, to no operator that the limit of spee reached Without breaking the ci vices instrumental in operation of hicle. For this purpose we have provided shy-pass partial circuit shown as an electric conductor 102, having connection with the terminal 72 and a terminal 103 of av switch 104 which is located in the electric conductor 94;. By means of this switch eiectric c ductor 94 may be interrupted end oir' cuit closed with the partial circuit 3; I mean" "l -plug,- circuit is rendered.independent of control. by the making or breaking of the terminals 72, 74. It is understood that a suitable tiniing device for the sparloplug circuit is pro vided whereby the sparking is effected in proper relation to piston travel. This is however not shown because well known.

Having thus fully described our invention, what We claim as new and desire to secure by Letters Patent is:
